Abstract: A freight car is constructed with an undercarriage having a flat cargo floor and with an upright fixed end wall at each end of the floor. A gantry in the form of an arch extends upwardly from the floor substantially centrally between the end walls and a hood support rail extends between the fixed end walls on each side of the floor. The space above the floor is covered by a hood which is of a length to extend between the gantry and one end wall and which includes a roof portion which overlies the gantry and the one end wall and side wall portions which extend downwardly from each side of the roof. The side wall portions carry rollers or casters which are engageable with the rail for supporting the hood for movement along the rail. The hood may be moved when it is in an open position along the rail for example to completely uncover the space between the gantry and one end wall.

Abstract: A bunker closure door mechanism for a bunker housing which has an opening with a seat around the opening which is closed by a closure door body, comprises, first and second spaced apart end levers which are pivotally connected between the housing and one end of the door. In addition, central levers are pivotally connected to the door body intermediate its length and pivotally connected at their opposite ends to a toggle lever which is pivotally mounted on the housing. The door body carries guide pins which are engageable in vertical slots of guide members supported on the bunker housing. By means of an actuator in the form of a fluid-pressure operated piston and cylinder connection, a guide rod is actuated to engage the central lever intermediate its length and to pivot it about its connection to the toggle lever and to also shift the toggle lever over its dead center position.

Abstract: The valve construction comprises a valve housing which has a housing flow passage therethrough and an intermediate spherical valve chamber in the passage. A pivot member which has concentric end journal portions is rotatably mounted in the housing and has an intermediate eccentric portion which is offset from the end journal portions and is located in the valve chamber. A spherically shaped globe valve member having a valve flow passage therethrough opening at respectively diametrically opposite ends of the valve member is rotatably supported on the eccentric portion which extends through diametrically opposite walls of the globe valve member which has an axis at right angles to the axis of the valve flow path. A dog carried on the globe valve member projects outwardly therefrom into a groove of the housing and limits the movement of the globe valve member relative to the pivot to 90.degree.. The valve is opened by pivoting the pivot member to cause a pin which is carried on the globe member to ride in a 90.

Abstract: The sliding wall includes a central wall section and two end wall sections, with the sections being co-planar in the closed state and movable, transversely of the car, out of the closing plane and into a shifting plane in which they are displaceable longitudinally of the car past closed wall sections. During shifting, the sliding wall sections are supported by rollers engageable with a rail, provided in an upper longitudinal stringer, and with the outer lateral surface of an outer lower longitudinal supporting beam, the stringer and the supporting beam forming, in cooperation with two corner posts, a side frame of the freight car. The upper rail is a single rectilinear and uninterrupted rail extending substantially the full length of the upper stringer. Each end section has, in the upper portion of its end adjacent the central section, an outwardly opening pocket having a horizontal catch member extending thereacross.
